I've never shot the current issue handgun of the US Military. I need to remedy that. Or at least familiarize myself with it's feature and how to field strip it. That can be done with some research.
When I was in the Navy, the issue handgun was the Beretta 92 (aka M9, aka a lot of other variants of same...), but the Navy wasn't on the top of the list for the new pistol so we made do with M1911A1s. That's what I qualified on. I am pretty familiar with the 1911 at this point.
It looks simple enough. DA/SA, safety-decocker looks ambidestrous. The slide release and takedown lever thingy look ordinary and straight forward. 15 round magazines
Magazine safety? Can it fire with a round in the chamber but no magazine present? Dunno.
Field stripping... well, I can't figure that out unless I have one. But it looks easy. I'd just have to pay attention when taking it down to be sure I'd put stuff back in facing the correct direction. Look like 4 parts aside from the frame. Barrel, slide, guiderod, and spring. Easy enough.
